Abstract
L'invention concerne un transducteur électromagnétique comprenant un ensemble d'aimants (50) et une bobine d'excitation conductrice (52). Cet ensemble d'aimants engendre un champ magnétique d'émanation, au sein duquel se trouve la bobine d'excitation. Cette bobine d'excitation constitue une bobine en anneau plate ayant une largeur égale ou supérieure à sa hauteur. Telle qu'elle est assemblée, la bobine d'excitation est montée à proximité de l'ensemble d'aimants, de telle manière qu'un mouvement axial relatif peut se produire entre eux, pendant l'utilisation. Dans un mode de réalisation, l'ensemble d'aimants comprend deux aimants permanents sous forme de disques (64, 66) qui possèdent des magnétisations axiales et qui sont orientés avec des pôles similaires se faisant face, de manière à engendrer un champ magnétique d'émanation dans le sens radial. Dans un autre mode de réalisation, l'ensemble d'aimants comporte une paire d'aimants permanents en anneau aimantés axialement (64, 66), également orientés avec des pôles similaires qui se font face.
